Abstract

PURPOSE: To prevent the axial lag when the races are installed into the housing, by splitting the bearing race with V-shape.
CONSTITUTION: Splitting of bearing race 10 is carried out through that jigs 13, 14 are installed on the inner surface and outer surface and the race is pressed on the splitting line between upper die 7 and the lower die 6 of press after a notch 17 and guide hole 11, 12 have been made in the race 10. Special pin 3, 9 contacts with two portions on the circumferential surface of the guide hole 11, 12 simultaneously the outer race surface of bearing race 10 is pressed by a lower die 6 and upper die 7, concentrated stress is given at the contact portion. Consequently, bearing race 10 produces crack from the concentrated portion of stress on the notch 17 and the guide hole 11, 12 respectively, the race is splitted with V-shape by light splitting load of the press.
